The entire oxygen system must undergo degreasing and be strictly free of oil and debris, as oxygen applications require extremely high safety standards. The specifications of the oxygen heat exchanger adopted by our company are as follows: spiral-wound type, 304 stainless steel material, 12mm*1mm SUS304 seamless tubes, a sufficiently large heat exchange area, and a design pressure exceeding 0.6 MPa, along with other key design features.
